API Reference

Submit tool-call input

The App Management API is in beta. Endpoints, fields, and behavior may still change, so avoid depending on it in production.

Approves or rejects one tool call the AI builder is waiting on, then resumes the turn.

Some steps pause for you before they run. The turn stops with an assistant message whose tool call has no result yet, and the builder waits. Answer it here to let the turn continue. Use Read conversation messages to find the tool call that is waiting and take its ID.

The request stays open until the resumed turn settles, so it can take several minutes. Resuming a turn consumes credits. To answer several waiting tool calls at once, use Submit tool-call input (batch).

A turn that fails still returns 200. Check status.state: error means the turn failed, and status.error_source says where. paywall there means you ran out of credits.

The response includes fields beyond the ones documented here. Don’t rely on undocumented response fields, as they can change at any time. Send only the fields documented here. Other request fields are not supported and their behavior can change.

Authorizations

api_key

string

header

required

Personal API key.

Path Parameters

app_id

string

required

ID of the app whose builder chat this request acts on.

Body

application/json

tool_call_id

string

required

ID of the tool call to answer. Read it off the waiting assistant message returned by Read conversation messages.

Example:

"toolu_01A9FJd3kP2mNqRs7VwXyZ4b"

action

enum<string>

required

Whether to let the tool call run or turn it down. Rejecting tells the builder to continue without doing that step.

Available options:

approved,

rejected

Example:

"approved"

message_id

string

ID of the message the tool call belongs to. Some tools use it to report progress.

Example:

"7f3a1c88-52d4-4a0e-9b31-2c6f0d8e4a19"

Response

The app once the resumed turn finished.

The app document the chat endpoints return once a turn settles.

The real payload is the whole app document, so this is a strict subset: the fields a caller needs to see what the turn did and whether it succeeded.

string | null

ID of the app.

Example:

"6820f3a4e7b91d003c45a1f2"

name

string | null

Display name of the app.

Example:

"My CRM"

status

AppStatusResponse · object | null

The app's build status once the request returned. Read state to tell a finished turn from one that is still processing or that failed.

Show child attributes

conversation

ChatTurnConversation · object | null

The app's conversation, including the messages this request produced.
